Writing effective Use Case Examples. School of Informatics Courses: SEOC 2009/10 Lecture Notes. Use cases. Hi I have a question: How do you write a use case when the functionality to be achieved has been decided before hand to be achieved by an off the shelf tool? The dev team still wants the use case. So what would be the use case level i should be following and how should i write the steps involved? Thanks -by Atalichome on 8/2/2009 at 11:33 PM There are two ways to read the question.. the functionality (or process/function) has been decided to be that of the COTS system provided.
In the first case, simply give them the vendor manuals. The second case is different. Hope this helps -by LK on 8/5/2009 at 11:56 AM I have written a use case relating to ‘intake and eligibility determination’ that is supported primarily by a web-based user interface. -by AD on 2/25/2010 at 2:07 PM I’d try for using an extension or Technology & Data Variations to avoid writing a separate use case.

Humans and Technology Document TR.96.03a, April 26, 1996, October 26, 1998 Version 1: April 26, 1996 Version 2: October 26, 1998 Note 2001: In my book Writing Effective Use Cases I made a couple of small changes to these templates, most notably renaming “Failed End Condition” to the more correct ”Minimal Guarantee” and “Subvariation” to the more correct ”Technology and Data Variations List.”
The book discusses the meaning of these more correct terms. Since most of the action is in the scenario writing, the template as placed in this file will still do you good. Note Oct 2008: template formatting screwed up by Media-Wiki. see if still has the old versions in the pdf file. The template has the sections: name (which is the goal), goal in context, scope, level, trigger, pre- and postconditions, main course, extensions, sub-variations, and other characteristic data for the use case.
Using, Staging, Tailoring the Template 1. Use case fundamentals. Updates Scope & Levels description, to show 4 design scope levels, that goals can be written at any level for any design scope. (sorry for not detecting the error in the previous versions of the document earlier) Good article. I don’t think I quite understand the subtletees between System Scope and Strategic Scope, and I’ve been writing Use Cases for years!!
Maybe I’m not reading it right or maybe this could do with some better examples. Talking of examples more real life (less technical examples) would be nice. “Add device to database” – whats that all about? How about “check my account balance”! Another thing that got me thinking was “logging in” as a sub-function? But as I said, good article. -by Mark on 10/6/2009 at 11:06 AM Great artical.I like it. -by Yvonne on 10/21/2009 at 5:43 AM Really nice article, it explains use cases in a really understandable way. -by Alexander on 3/21/2010 at 10:18 AM Hello Alistair, My question is about the section ‘Alternate Flows’ vs ‘Extensions’. 1. 2. 3. MDD.
Mark Brunelli, News Writer Published: 10 Aug 2004 When you register, you'll begin receiving targeted emails from my team of award-winning writers. Our goal is to keep you informed on recent service-oriented architecture (SOA) and SOA-related topics such as integration, governance, Web services, Cloud and more. What is MDD? You have model-driven development [MDD] and then you also have model-driven architecture [MDA] .
MDA is actually trademarked by the OMG [Object Management Group], which is sort of a consortium of vendors and end users that is developing standards for implementing MDD. MDD is comprised of being able to visualize code, and the MDA specification that does that is the Unified Modeling Language , or UML. The Holy Grail is to allow business analysts to directly contribute to a model, and have architects and developers contribute to the model. It's basically to graphically represent code syntax and code concepts or domain concepts and structures. OO Design Patterns. Requirements.pdf (application/pdf objekt)

Be Realistic About the UML: It's Simply Not Sufficient. The UML is Not Sufficient AM's Multiple Models principle tells you that you need to have many modeling techniques in your intellectual toolkit if you want to be effective as a developer. The article Artifacts for AM presents an overview of many common modeling artifacts, including but not limited to those of the Unified Modeling Language (UML), and as you can see there is a wide selection of models available to you.
Each model has its strengths and weaknesses, therefore no single model is sufficient for all of your software development needs. Although the UML is in fact quite robust, the reality is that it isn't sufficient for your modeling needs. For example, when I design the user interface of an application I generally like to create a user interface flow diagram, an example of which is shown in Figure 1. Figure 1. Figure 2. Similarly, the UML does not yet provide a standard way of modeling web service "wiring diagrams" nor does it say anything about security threat modeling.
Rezervace K333. Introduction to Object-Orientation and the UML. The prevalence of programming languages such as Java, C++, Object Pascal, C#, and Visual Basic make it incredibly clear that object-oriented technology has become the approach of choice for new development projects. Although procedural languages such as COBOL and PL/1 will likely be with us for decades it is clear that most organizations now consider these environments as legacy technologies that must be maintained and ideally retired at some point. Progress marches on. My experience is that agile software developers, be they application developers or Agile DBAs, must minimally have an understanding of object orientation if they are to be effective. This includes understanding basic concepts such as inheritance, polymorphism, and object persistence. Furthermore, all developers should have a basic understanding of the industry-standard Unified Modeling Language (UML).
